[0021] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0022] Example 1, refer to Figures 1 to 6, which is the first embodiment of the present invention. This embodiment provides an LED display detection device that can automatically dry the residual water on the surface of the display after waterproof detection. It includes a detection mechanism 1, which includes a support body 11. A slide rail 12 and a water collecting basin 13 are installed on the support body 11. The slide rail 12 is located above the water collecting basin 13. A spray head 14 is connected to the slide rail 12. The spray head 14 can move under the control of the slide rail 12 and can be adjusted in angle. The spray head 14 is connected to the water collecting basin 13 through a pipeline and a water pump. A water wiping mechanism 2 is provided at the top of the support body 11. The water wiping mechanism 2 includes a concave frame 21 provided at the top of the support body 11. The concave frame 21 can be connected to the slide rail 12 or fixedly installed on the support body 11. Preferably, it is installed on the slide rail 12 and its position can be adjusted through the slide rail 12. A first mounting block 22 and a second mounting block 23 are provided on the side of the concave frame 21. A sliding component 24 is provided between the first mounting block 22 and the second mounting block 23. A water wiping cloth 25 is provided on the sliding component 24. Squeezing components 26 are provided on both the first mounting block 22 and the second mounting block 23. The squeezing components 26 are used to displace the water wiping cloth 25 from the display screen and at the same time squeeze the water wiping cloth 25 to squeeze the water on the water wiping cloth 25 and make it enter the interior of the water collecting basin 13. Both the first mounting block 22 and the second mounting block 23 are connected to an adjusting component 27; Among them, the spray head 14 is selected as an adjustable spray head 14, which can adjust different spraying angles and the amount of sprayed water to simulate rain in reality; Among them, the concave frame 21 is in an inverted "concave" shape. Both the first mounting block 22 and the second mounting block 23 are provided inside the concave part of the concave frame 21, and the first mounting block 22 and the second mounting block 23 are on the same horizontal plane; Through the adjusting component 27, the first mounting block 22 and the second mounting block 23 can be driven to move up and down. The first mounting block 22 and the second mounting block 23 drive the height of the sliding component 24 to move up and down, so that the sliding component 24 drives the water wiping cloth 25 to dry the residual water on the surface of the display screen. At the same time, when the first mounting block 22 and the second mounting block 23 move to the bottommost position, the squeezing component 26 is driven to operate, not only squeezing the water on the water wiping cloth 25, but also preventing the water wiping cloth 25 from contacting the surface of the display screen during the rising process, reducing the wear of the display screen and the water wiping cloth 25, and at the same time increasing the electrical performance test efficiency of the display screen.

[0023] Further, the sliding component 24 includes a cross plate 241 disposed between the first mounting block 22 and the second mounting block 23. The water wiping cloth 25 is sleeved on the cross plate 241. Installation grooves 242 are formed inside both the first mounting block 22 and the second mounting block 23. Sliders 243 are provided inside both of the two installation grooves 242. Telescopic rods 244 and springs 245 are connected to both of the two sliders 243. The springs 245 are sleeved on the surfaces of the telescopic rods 244. One ends of the springs 245 and the telescopic rods 244 away from the sliders 243 are connected to the inner walls of the installation grooves 242. Two pressing components 26 are respectively located inside the two installation grooves 242.

[0024] Further, the adjusting component 27 includes a driving motor 271 disposed on the top of the concave frame 21. The output end of the driving motor 271 penetrates through the concave frame 21 and is connected to a threaded rod 272. One end of the threaded rod 272 away from the driving motor 271 is rotationally connected to the concave frame 21 through a rotating shaft. A smooth rod 273 is disposed on one side of the concave frame 21 away from the threaded rod 272. Both ends of the smooth rod 273 are fixedly connected to the concave frame 21. Both the smooth rod 273 and the threaded rod 272 are vertically arranged. The first mounting block 22 is sleeved on the surface of the threaded rod 272 and is threadedly connected to the threaded rod 272. The second mounting block 23 is slidably sleeved on the surface of the smooth rod 273.

[0025] Further, an installation member 111 is further provided on the support body 11. The installation member 111 is used for installing the display screen. The installation member 111 can be a conventional fixture.

[0026] In this embodiment, the water wiping cloth 25 is fixedly sleeved on the surface of the cross plate 241. In the initial state, there is a certain amount of water in the water collecting basin 13. When in use, first install the display screen on the top of the installation member 111. After completion, turn on the water pump, so that the water pump pumps out the water in the water collecting basin 13 through the pipeline and sprays it on the surface of the display screen through the nozzle 14, simulating the situation in reality to perform multi-angle and different water spraying amounts on the display screen, detecting the sealing performance of the display screen and the waterproof performance of the power supply part, observing the sealing performance of the display screen frame part and using a leakage detector to detect whether there is leakage at the power supply connection and the electrical performance under the energized state. After the detection is completed, by turning on the driving motor 271, the driving motor 271 drives the threaded rod 272 to rotate. The threaded rod 272 drives the first mounting block 22 to move. Under the cooperative action of the two sliders 243, the cross plate 241 and the second mounting block 23 sleeved on the smooth rod 273, the threaded rod 272 drives the first mounting block 22 to descend, and the second mounting block 23 slides downward along the smooth rod 273 accordingly. At the same time, the first mounting block 22 and the second mounting block 23 respectively drive the cross plate 241 to descend through the two sliders 243, and the cross plate 241 drives the water wiping cloth 25 to descend, realizing the wiping of the residual water on the surface of the display screen.

[0027] In summary, in this embodiment, a structure for wiping residual water from the surface of a display screen is provided. When the electrical performance test of the display screen is completed, the wiping cloth 25 is driven by the driving motor 271 to descend. The residual water on the surface of the display screen is wiped away, which reduces the work intensity of the staff, reduces the problem of the display screen being damaged due to excessive force by the staff when the display screen is wiped manually, and avoids the risk of electric shock to the staff when the display screen leaks electricity.

[0028] Example 2, reference Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an extrusion assembly 26 of the LED display screen detection device, which solves the problem that the wiping cloth 25 contacts the display screen when it rises, thereby increasing the wear of the display screen surface. The extrusion assembly 26 includes a vertical bar 261 vertically arranged inside the mounting groove 242, and both ends of the vertical bar 261 that are far away from each other slide through the mounting groove 242. The vertical bar 261 is provided with a first protruding block 262, and the first protruding block 262 is provided with a first inclined surface 263 and a first plane 264; Among them, the mounting groove 242 matches the extrusion assembly 26, and the vertical bar 261 can slide vertically up and down along the mounting groove 242. The setting of the first protrusion block 262 limits the highest position and the lowest position that the vertical bar 261 can move, ensuring the connection between the vertical bar 261 and the mounting groove 242, so that the vertical bar 261 will not be completely detached from the inside of the mounting groove 242.

[0029] Furthermore, the extrusion assembly 26 also includes a notch 265 formed on the slider 243 . The driving block passes through the notch 265 . A second inclined surface 267 and a second plane 268 are provided on the notch 265 . The second inclined surface 267 matches the first inclined surface 263 .

[0030] In this embodiment, in the initial state, the first inclined surface 263 of the first protruding block 262 can contact the second inclined surface 267 of the notch 265; When in use, when the first mounting block 22 and the second mounting block 23 descend to a certain position, at this time, the vertical bars 261 on the first mounting block 22 and the second mounting block 23 both contact the bottom of the concave frame 21. As the first mounting block 22 and the second mounting block 23 continue to descend, the two vertical bars 261 rise simultaneously. The two first inclined surfaces 263 on the two vertical bars 261 respectively press the two second inclined surfaces 267 of the two notches 265 on the two sliders 243, causing the two sliders 243 to move away from the display screen. The two sliders 243 drive and respectively press the two springs 245, causing the two springs 245 to contract. Under the action of the telescopic rod 244, the stability of the expansion and contraction of the two springs 245 is ensured. At the same time, the two sliders 243 drive the water wiping cloth 25 to move away from the display screen through the cross plate 241. When the first flat surface 264 on the first protruding block 262 contacts the second flat surface 268 of the notch 265, at this time, the water wiping cloth 25 no longer contacts the surface of the display screen, and the first mounting block 22 and the second mounting block 23 move to the bottommost position. The settings of the first flat surface 264 and the second flat surface 268, and in cooperation with the mounting groove 242 and the vertical bar 261, and under the extrusion of the spring 245 through the second flat surface 268 at the slider 243 and the notch 265, the vertical bar 261 cannot descend, thereby preventing the slider 243 from resetting; When the driving motor 271 drives the first mounting block 22 and the second mounting block 23 to rise through the threaded rod 272, and the first mounting block 22 and the second mounting block 23 drive the water wiping cloth 25 to rise through the two sliders 243 and the cross plate 241, the water wiping cloth 25 will not contact the surface of the display screen. Thus, the wear of the display screen is reduced. When the first mounting block 22 and the second mounting block 23 move to the topmost position, at this time, the two vertical bars 261 both contact the top of the concave frame 21, causing the two vertical bars 261 to descend. Then, under the action of the two springs 245. The two sliders 243 reset, the two sliders 243 drive the cross plate 241 to reset, and the cross plate 241 drives the water wiping cloth 25 to reset, causing the water wiping cloth 25 to return to the initial position.

[0031] In summary, in this embodiment, a squeezing component 26 is mainly provided, so that the water wiping cloth 25 does not contact the surface of the display screen during the ascending process. Thereby, the problem of wear of the display screen and the water wiping cloth 25 is reduced. Although in the prior art, the position of the display screen can be adjusted to avoid the wear problem between the water wiping cloth 25 and the display screen after the water on the surface of the display screen is wiped dry, this will add a step of adjusting the position of the display screen. In the present solution, when the device moves to the bottommost position, at this time, the water wiping cloth 25 has completed wiping the water on the surface of the display screen, so the water wiping cloth 25 can directly return to the initial position. Even if it has not completed wiping the water, when the display screen still needs to be wiped again, the water wiping cloth 25 also needs to wipe the surface of the display screen from the top. Otherwise, when wiping from the bottom, the water will accumulate on the top of the water wiping cloth 25 and the wiping effect cannot be achieved. If the display screen still needs to be wiped dry, the position of the display screen needs to be adjusted, which is rather cumbersome. The setting of the present solution reduces the step of adjusting the position of the display screen when the water wiping cloth 25 has completed wiping the surface of the display screen, thereby improving the processing efficiency of detecting the display screen and facilitating the detection of the display screen.

[0032] Embodiment 3. Referring to Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a squeezing component 26 of the LED display screen detection device, which improves the effect of the water wiping cloth 25 wiping the water on the surface of the display screen. The squeezing component 26 further includes a second protruding block 269 connected to the vertical bar 261. A third plane 2610 is provided on the second protruding block 269. The distance between the third plane 2610 and the vertical bar 261 is equal to the distance between the first plane 264 and the vertical bar 261. A fourth plane 2611 is provided on the notch 265. The distance between the second plane 268 and the fourth plane 2611 is equal to the distance between the third plane 2610 and the vertical bar 261. That is, when the third plane 2610 on the second protruding block 269 contacts the fourth plane 2611 of the notch 265, the side of the vertical bar 261 away from the second protruding block 269 contacts the second plane 268 of the notch 265. When the first plane 264 on the first protruding block 262 contacts the second plane 268 of the notch 265, at this time, the side of the vertical bar 261 away from the first plane 264 contacts the fourth plane 2611 of the notch 265.

[0033] Furthermore, the squeezing component 26 further includes a third inclined plane 2612 provided on the second protruding block 269 and a fourth inclined plane 2613 provided on the notch 265, and the third inclined plane 2612 matches the fourth inclined plane 2613; Among them, since the elastic force of the spring 245 will decrease after long-term use, when the elastic force of the spring 245 cannot drive the water wiping cloth 25 back to the initial position through the slider 243 and the cross plate 241, at this time, when the vertical bar 261 descends, the vertical bar 261 squeezes the fourth inclined plane 2613 of the notch 265 through the third inclined plane 2612 to drive the slider 243 back to the initial position, and then the slider 243 drives the water wiping cloth 25 back to the initial position through the cross plate 241.

[0034] All other structures are the same as those in Embodiment 2.

[0035] Different from the second embodiment, in this embodiment, in the initial state, there is a certain distance between the first inclined plane 263 on the first protruding block 262 and the second inclined plane 267 of the notch 265, and in the initial state, the bottom of the first protruding block 262 is in contact with the inner wall of the bottom of the installation groove 242. At the same time, the third plane 2610 on the second protruding block 269 is in contact with the fourth plane 2611 of the notch 265, and the side of the vertical bar 261 away from the second protruding block 269 is in contact with the second plane 268 of the notch 265; When in use, when the water wiping cloth 25 dries the surface of the display screen, the water wiping cloth 25 has a certain contact force with the surface of the display screen, and under the action of the elastic force of the water wiping cloth 25, it will drive the slider 243 to move away from the display screen through the cross plate 241. And under the combined action of the side plane of the vertical bar 261 and the second plane 268 of the notch 265 and the third plane 2610 of the second protruding block 269 and the fourth plane 2611 of the notch 265, the slider 243 cannot move, thereby ensuring the contact effect between the water wiping cloth 25 and the display screen and increasing the drying effect of the water wiping cloth 25 on the moisture of the display screen. When the first mounting block 22 and the second mounting block 23 move to the appropriate positions, the bottoms of the two vertical bars 261 are in contact with the concave frame. Thereby causing the two vertical bars 261 to rise, and the two vertical bars 261 drive the first protruding block 262 and the second protruding block 269 thereon to rise simultaneously. When the third plane 2610 on the second protruding block 269 is completely misaligned with the fourth plane 2611 of the notch 265, at this time, the first inclined plane 263 on the first protruding block 262 is in contact with the second inclined plane 267 of the notch 265. As the vertical bar 261 continues to rise, it drives the slider 243 to move away from the display screen. When the side of the vertical bar 261 away from the first protruding block 262 is in contact with the fourth plane 2611 of the notch 265, and the first plane 264 on the first protruding block 262 is in contact with the second plane 268 on the notch 265, at this time the water wiping cloth 25 is completely misaligned with the display screen; When the top of the vertical bar 261 comes into contact with the top of the concave frame 21, the vertical bar 261 descends at this time. The vertical bar 261 drives the first protruding block 262 and the second protruding block 269 to descend simultaneously. When the first plane 264 on the first protruding block 262 is misaligned with the second plane 268 on the notch 265. At this time, the spring 245 drives the slider 243 to reset. And as the vertical bar 261 continues to contact the top of the concave frame 21, the vertical bar 261 drives the second protruding block 269 to descend, so that the third inclined plane 2612 on the second protruding block 269 presses the fourth inclined plane 2613 of the notch 265, thereby accelerating the reset speed of the slider 243, and enabling the slider 243 to drive the water wiping cloth 25 back to the initial position through the cross plate 241.

[0036] In summary, in this embodiment, the optimization of the water wiping cloth 25 for drying the moisture on the surface of the display screen is further carried out, so that the water wiping cloth 25 can stably contact the surface of the display screen, ensuring the efficiency of drying the moisture on the surface of the display screen, and thus increasing the detection efficiency of the display screen.

[0037] Embodiment 4, referring to Figures 1 to 7 , is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a pressing assembly 26 of the LED display screen detection device, which solves the problem of the water adsorbed on the water wiping cloth 25. The pressing assembly 26 further includes a vertical rod 2614 fixedly installed on the inner wall of the installation groove 242. A right-angle plate 2615 is slidably sleeved on the surface of the cross plate 241. One end of the right-angle plate 2615 extends into the installation groove 242, and an inclined groove 266 is formed on the right-angle plate 2615. The vertical rod 2614 slidably penetrates through the inclined groove 266.

[0038] Furthermore, the water wiping cloth 25 is made of an elastic material, that is, a conventional sponge can be used, which has low cost, good water absorption, and large elasticity.

[0039] The rest of the structure is the same as that of Embodiment 3.

[0040] Different from the first embodiment, in this embodiment, the water wiping cloth 25 is slidably sleeved on the surface of the cross plate 241, and the two ends of the water wiping cloth 25 away from each other are respectively fixedly connected to the two right-angle plates 2615; When the two sliders 243 move away from the display screen, the two sliders 243 drive the water-wiping cloth 25 and the two right-angle plates 2615 to move away from the display screen through the cross plate 241. At the same time, the inclined grooves 266 on the two right-angle plates 2615 are respectively in contact with the vertical rods 2614 inside the two installation grooves 242. Under the action of the vertical rods 2614, the two right-angle plates 2615 approach each other, thereby causing the two right-angle plates 2615 to squeeze the water-wiping cloth 25, squeezing out the water on the water-wiping cloth 25. The water automatically falls into the water collecting basin 13, saving water resources and facilitating the subsequent drying of the surfaces of other display screens by the water-wiping cloth 25.

[0041] In summary, in this embodiment, the optimization of the drying of the residual water on the display screen by the water-wiping cloth 25 is further carried out, so that after the water-wiping cloth 25 dries the surface of the display screen, the water adsorbed on the water-wiping cloth 25 is squeezed out, so that when the water-wiping cloth 25 dries the surfaces of other display screens subsequently, there will not be too much water remaining on the water-wiping cloth 25, resulting in the situation that the drying effect of the water-wiping cloth 25 on the subsequent display screens becomes worse and worse.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
